Sampling Start Bit
A508.15
When a data trace is started by turning this bit ON from
the CX-Programmer, the PLC will begin storing data in
Trace Memory by one of the three following methods:
Data is sampled at regular intervals (10 to 2,550 ms).
Data is sampled when TRSM(045) is executed in the
program.
Data is sampled at the end of every cycle.
Read/write
Trace Start Bit
A508.14
Turn this bit ON to establish the trigger condition. The
offset indicated by the delay value (positive or negative)
determines which data samples are valid.
Read/write
Trace Busy Flag
A508.13
ON when the Sampling Start Bit (A508.15) is turned ON.
OFF when the trace is completed.
Read/write
Trace Completed Flag
A508.12
ON when sampling of a region of trace memory has been
completed during execution of a trace.
Read/write
Trace Trigger Monitor Flag
A508.11
ON when a trigger condition is established by the Trace
Start Bit (A508.14). OFF when the next data trace is
started by the Sampling Start Bit (A508.15).
